Axle-nut lock.



WILLIAM H. SHUTER, OF MAYWOOD, ILLINOIS.

specification of Letters Patent.

Patented Dec. 5, 1911.

Application led February 27, 1911. Serial No. 611,152.

To all whom 'it may concern.'

Be it known that I, WILLIAM H. SHUTER, a citizen of the United States, residing at Maywood, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Axle-Nut Locks, of which the following is a specification.

This invention relates to means .for locking axle nuts, and is particularly applicable to farm and heavy delivery wagons.

An lobject of the present invention is to provide means which shall not simply prevent the nut from being accidentally rotated ofi' the axle, but which shall also prevent any movement of the nut, since, if the nut is free to move even slightly, the co-ntinued pressure of the hub is likely tov cause the threads of the nut `or the axle to be stripped.

A further object of the invention is to produce an axle-nut lock which may be readily applied to axles having metallic skeins.

In the accompanying drawings, Figure 1 is a longitudinal, vertical, central section through one end of an axle provided with a nut lock embodying the features of my invention. Fig. 2 is a left-hand end elevation of the parts shown in Fig. 1.

In the drawings, 1 represents the outer end of one member of the axle, which member may, if desired, be made of wood. Fitting upon the member 1 is a skein 2, the outer end 3 of which skein is pro-vided with an opening 4t therethrough to receive a bolt 5. The screw-threaded portion of said bolt engages the member l, the head of the bolt bearing against the outer end/of the portion 3, whereby the skein 2 is secured to the member l.

7 is a nut turned upon the screw-threaded periphery of the portion 8. To secure the nut 7 in place, I provide a locking staple 8 having legs of unequal length, the longer leg 9 of said staple extendingthrough an opening 10 in the bolt head 6, while the shorter leg 11 extends through registering openings 12 and 13 in the nut 7 and the portion 3, respectively. It will be seen that when the staple V8 occupies the position shown in the drawings, the nut 7 is securely held against any movement whatsoever upon the portion 3 whereby the pressure of the wheel hub 14 is prevented from unscrewing the nut or stripping the threads thereof. To remove the staple 8, the lower end of the leg 9 may be given an upward tap to withdraw the leg 11 from the openings 12 and 13. It will be seen that the single device 8 serves to lock both the axle nut 7 and the bolt 5 against rotation.

I claim as my invention:

1. The combination of an axle having an outer exteriorly-screw-threaded end and an end, a bolt extending through saidk screwthreaded end and engaging said axle member, the head of said bolt bearing against the outer end of said screw-threaded portion, a nut turned upon said screw-threaded k'portion, and a staple, one leg of which extends through registeringopenings in said nut and said screw-threaded portion, the other leg of said staple extending through an opening in the head of said bolt.

In testimony whereof I aiiix my signature in presence of two witnesses.

WILLIAM II. SHUTER.
